Lette/rs Patent No. 91,729, dated June 22, 1869.

IMPROVEMENT IN' FELTING-MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it lmay concern Be it known that I, ItUDoLiT1 EICKEMEYER,of Yonkers, in the county of Westchester, and State of New York, haveinvented certain new and useful Improvements in Machinery for FeltiugFelt Cloths; and Ido hereby declare that thelfollowing is a full andcorrect description thereof, reference being had to the accompanyingdrawings, forming apart of this speeitication, and to the letters ofuiterf-ence thereon.

This invention relates to jiggering-machines, in which the material isfed upon a,-car`rying-cloth between a fiat-surfaced jigger anda platen.

In some ofthe jiggering-machines of this class, the jigger'has acontinuous action upon the abridand the carrying-cloth or conductor hasa slow continuous motion, but such machines do not admit of applying thejiggering-surface to the fabric under heavy pressure,and consequentlyare only suitable for hardening the fabric, preparatory to thesubsequent operation of the fulling-mill. In other machines of thisclass, the jiggering-apparatus is applied to the fabric, while thecarrying-cloth is atrest, and the jiggerin-g proceeded with for a periodof time regulatedlbythe machinery when it ceases, and the fabric ismoved forward about the distance of thevwidth of thejiggering-apparatus,

and the jiggering again proceeded with, these ope'rations beingrepeated. to felt a continuons fabric; but such machines necessarilyproduce unevenly-elted fabrics, because the entire surface of `thefabric is not subjected to the action of all part fof `the jiggeringsurface, and because the speed of t e: jig-ger and the heat and moisturemay. vary upon the successive squares of the fabric successivelyiapted,upon by the i i v v ltolremedy the defeets last mentioned, .and toproducel evenly-felted fabrics, progressively felted bythe operation ofthe machine. rllhis is accomplishedy bycombining with The object of thisinvention the mechanism that regulates the periodici time dur ing whichthe jigger acts upon the fabric to be felted, a mechanism which movesthe fabric forward with the carrying-cloth a short distance comparedwith the width of the jiggering-surfaces, whenever the fabric .isreleased from the action of the ,jggering-surface,

has repeated its action upon the fa ric and retreated therefrom, theseoperations bein |repeated until the desired length of fabric is felted.

and then remains at rest until thegjiggering-smface By this mode ofoperation, all parts of the jiggen' ing-surface are applied to all partsof the fabric passing through the machine during regular and uniformpeliods of time, and the fabric thereby becomes uuiforrnly felted. v ,uJ

This invention further consists; in combining, with the fe1ting-platen,carrying-cloth,lland. liat-surfaced uiigger, a system of rotatingcamsanilweighted levers ,ftl l connected with the jigger, substantiallyas hereinafter described, whereby the jiggering-suriace is pressed uponthe fabric with a determinate pressure during regular periods of time,and released from the fabric at regular intervals, in order to permit ofthe intermittent progressive movement of tl1e'carrying-eloth.

Figure 1 of the drawings represents a longitudinal section of themachine;

Figure 2, au end view; and

Figure 3,' a plan view of the same.

lhe side frames c. a ofthe machine are framed together by thecross-braces a2 a3 ai.

The platen b is secured to the side flames by the screws b* b2 Ifi biThe carrying-cloth c is an endless apron or conductor, of linen, canvas,or other suitable material for a hardening-cloth, extended over thedrums l d d di,

and moved intermittently at regular intervals, a short distance,compared v-:itn the width of the platen, inthe direction indicated bythe arrows, by a pawl, e, and ratchet e', the latter attached to the`shaft of the drum d.

The flat jigger-plate f forms the top plate of the steam-box f l, andisperforated with fine holes to permit steam to pass to the fabric to befelted.

The steam-box yI has suitable induction and eduction-pipes fzf, (shownbroken olf,) which should he connected, by flexible conuectingepipes,with a source of supply of steam and a waste-water receptacle. Thissteam-box, with its tiatrubbing-surfaee, is placed beneath the platen,under that portion of the carrying-cloth in contact therewith, andreceives a very short and exceedingly rapid reciprocating motion fromthe crank-shaft g, which may be driven as usual by a rapid belt from aseparate counter-shaft overhead,

.running upon the driving-pulley gl, and is connectedv with thesteam-box j, by two connecting-rods, g2 g3. At each side of thejiggering steam-box, are guides g g5, which do notvinterlere with itsbeing moved to' ward and from the feltiug-eylinder.

rEhe steam-box and its jiggering-surface are moved up and down, and heldagainst the hardening-cloth and felting-cylinder with a yieldingpressure, by mechanism, as follows, viz:

The steam-box is supported by four rocking eolumns, two of which, 71.hl, are connected by joints to lugs or projections from the lower partof a sliding plate, t, which slides up and down Within the frame uponthe side frame a, the upper part of the sliding plate c' having-aguide-bar, i?, projecting upward from it, which slides in a recess inthe end of the cross-braee a, the lower part of the sliding plate beingguided by the camshaft, which passes through a slot made in the middleof the lower part of the plate for that purpose; and the other twocolumns, one only, hshown in the drawings, are similarly connected to anoppo-
